Yellow Wheel Casters

Yellow usually marks a high-capacity polyurethane compound. The color signals a heavy-duty tread engineered to carry serious loads, 1,500 to 4,200 lbs per caster here, while keeping polyurethane's quiet, non-marking, floor-friendly rolling.

Yes. Like other quality polyurethane wheels, yellow treads are non-marking and floor-friendly, protecting finished and sealed floors. That is a key advantage over cast iron, which carries similar loads but marks floors and runs loud.

These range from about 1,500 to 4,200 lbs per caster. The heavy-duty polyurethane carries loads approaching metal-wheel capacity. Divide your total load across all casters and add a safety margin, sizing up the wheel for heavier loads.

Yellow polyurethane carries nearly as much weight as cast iron while rolling quieter, protecting floors, and gripping better. Cast iron still wins for extreme heat or floors covered in sharp debris, but for heavy carts on finished floors, yellow polyurethane is usually the smarter choice.

The yellow polyurethane tread carries loads that approach metal-wheel territory while solving metal's problems: it rolls quietly, will not mark floors, and grips for controlled stops. Bonded to a steel or iron core, it combines the cushioning and traction of urethane with the load capacity of a metal-core wheel. For heavy carts that move across finished floors all day, yellow wheel casters deliver the capacity you need without the noise or floor scoring of cast iron.

Yellow wheel casters in this collection carry 1,500 to 4,200 lbs per caster across a range of wheel sizes, in swivel, rigid, and brake configurations. The non-marking polyurethane suits finished factory floors, while the heavy capacity handles loaded carts and equipment. Build a four-caster set with rigid and swivel casters for stable, steerable heavy carts, adding brakes where needed.
